Y @Jfvffm Patented Oct. 8, 1929 ROBERT IB. ADAMS, F LONSDALE, RHODE ISLAND ROOEING SHINGLE Application led January 4, 1928. Serial No. 244,460.

This invention relates to flexible roofing shingles, and has more particular reference to improvements in l the type of shingle shown in my U. S. Patent No. 1,636,349, dated July 19, 1927.

The primary object of the present invention is to improve the form of shingle shown in my above mentioned patent, whereby a greater lapping area and better nailing surface is provided.

A further object of the invention is to provide a' shingle which, by reason of the design thereof, maybe readily and economically cut from a strip of roofing material with a minimum of waste.

A still further object is to provide novel means for properly spacing the shingleswhile laying the same, and at the same time to provide improved means for fastening the outer and free ends of the exposed shinglel extensions to the body portions of the shingles directly below/ said extensions, in order to prevent the outer ends of said extensions from curling lupward 'under the g5 action of the elements, whereby more complete protection is afforded.

Theinventionconsists in the novel form, combination and arrangement of parts here inafterl more fully described, shown in the accompanying drawing and claimed. v

In the drawing:

Figure 1 is a plan' View of a portion of a roof covered with shingles constructed in accordance with the present invention; a5 lFigure 2 is a bottom plan view showing a pair of twin shingles constructed in accordance with the present invention, in interlocked operative relation;

Figure 3 is an enlarged section on line 3-3 of Figure 1; j Figure 4 is a diagrarnmaticalA plan view showing h ow the present vshingles can be economically cut from a strip of fiexible roofing material; Figure 5 is a detailed lan view of one ofl my improved twin shing es; and

Figure 6 is a detailed plan viewof a single 'shingle constructed in accordance with the present invention I0 As shown in the several views, each shingle or shingle unit comprises a rectangular body portion 5 of a suitable or desired width, and an extension 6 on and centrally of the lower edge ofthe body portion 5, the extension 6 being integral with the body portion and preferably substantially triangular in shape with the side edges thereof sloping at an angle of substantially 45 to the longitudinal axis ofthe body portion 5.

The length of each triangular extension 6 60 isprefera-bly somewhat less than the width of the body portionv5, and the width ofthe base of each extension 6 is preferably slightly less than the length of the body-portion 5, the extensions being slightly spaced from the ends of the body portion 5 as shown at 7 The apex of the triangular extension 6 is preferably blunted as at 8, integrally formed on this blunt apex edge of the triangular extension 6 is an arrow head tab 9 having a 79 relatively wide squared nose 10.

Slat-like iaps 11 are integrally formed on the sloping side edges of the extension 6, which correspondto the slats 12 in my above mentioned patent, and which are adapted to be under-turned'on the fold lines 12 as set forth in my said patent. l

As indicated in Figure 4, shingles of the above designmay be readily cut from strip, roofing material with practicall no loss of' 80 material, other than the small7 punchings made ,by cutting substantially triangular notches as at 13 to define the basis of the arrow head tabs`9 and to separate the same from the adjacent ends of the flaps 11.y It will also be noted that by providing the arrow head tabs 9 with squared noses, recesses will be form-ed as at 14 to space the extensions 6 at uniform distances from the ends of the body portion 5 and provide shoulders 9o at thepoints 7 which are transversely alined, so that the arrow head tab of one' shingle may be underturned about the shoulders 7 at ,adj acent ends of adjoining shingles as taught in my above mentioned patent. By dividing the strip of roofing material as at 15 at right angles to the length of the shingles andl at l vpoints intermediate alternate ones of the extensions 6, twin shingles will be formed as shown in Figures 1, 2, 4 and 5, and byv d tionally similarly severing the strip of'roofing material as indicated by dotted lines at 16 in Figure 4, single shingles of the'form shown in Figure 6 may be had.

It will be particularly noted that by forming the shingles with rectangular body portions, a greater lapping area will be had than by prvlding the ody portion of the shingle with sloping or u wardly converging end 1on1' side edges asin icated -at Band 3.-,inV my above mentioned patent, while considerable waste of material will be avoided. Moreover,

`by providing the' arrow head 'tabs 9 with squared noses, a better nailing surface-will be provided for said arrow head tabs, thereby facilitating laying and nailing ofthe shingles and effecting a more secure fastening of the same than is had with'the provision of pointed nosed arrow head tabs as disclosed in my above mentioned patent.

The manner of laying, assembling and fastening the shingles is substantially the same end directl over t e starter 18with the blunt edges 8 o the extensions .6 Hush with the outer or lower edge of said etartbr. .The starter 18 is provided for the purpose of filling they spacesbetween extensions in the lowest row of shingles. The iiaps 11 are underturned, and the arrow head tabs 9 are turned under the lower edge of the starter, the nails 15* being driven through the starter `andthel arrow head tab before the shingle proper is folded upwardly" and downwardly onto the roof for being nailed at 17. The arrow head tabs 9 of the shingles of the next upper-y row are then inserted under the shingles of the lower row at the shoulders 7, and nailed as at 15", whereupon said next row of shingles are laid onto the roof and nailed as at 17. This procedure is repeated for subsequent rows of shingles, and 1t will -bej seen that the extensions 6 will be leiectively against curling upward. f

at I claim as new is 1. A flexible roofing shin le comprising a.

rectangular body portion aving straight parallel end edges and formed on its lower edge with an integral triangular extension having vdownwardly converging side edges and terminating in a relative y ed apex, and a relatively small square-nosed `arrow headtab integrally formedl on the esame widthv narrow bluntv blunt apex edge of said extension, said shingle having folding sideianges which provide latera shouldersv for the arrow head tabs of shingles of the next upper course to seat against. s

2.. A flexible roofing shin 1e comprising a rectangular body portion aving straight parallel end` edges and formed on its lowerv edge with an integral triangular extension lhaving downwardly converging side edges and terminating inarelatively narrow blunted apex, and a relatively ysmall squarenosed arrow head tab integrally formed on the blunt apex edge of said extension, said triangular extenslon being of a length less than the width of the'body portion and being slightly spaced from the ends of the body and formed with folding side flanges which provide shoulders for the'arrow head tabs of shingles of the next upper Acourse to seat against.`

In testimony whereof I aiiix my signature.
